Last month, Apple announced that it will offer free battery replacement service for select iPhone 6S models after reports emerged that the 2015 flagship mobile had a cell glitch.

For the past several weeks, many iPhone 6S series owners have been facing random shutdown issues despite the device having sufficient battery power. Taking note of the issue, Apple initiated an investigation and it was found that a select batch of iPhone 6S series devices manufactured in September and October 2015 are the ones with faulty battery. It asked the affected users to return the device to the company's store and get the battery replaced free of cost.

Apparently this led to a large number of iPhone 6S owners visiting the Apple stores, as they didn't know when their device was actually manufactured. To help ease the confusion, Apple has now come up with an online tool on its support page, which helps the device owners know whether they are eligible for free battery service.

Owners just need to go to Apple's dedicated 'iPhone 6s Program' and type in their device's serial number and they will know whether they are eligible for free battery replacement or not.

Here's how to see serial number of Apple iPhone 6S:

Go to Settings >> General >> About and look for your device's serial number, IMEI/MEID, and ICCID. If you'd like to paste this information into Apple registration or support forms, tap and hold on the number and copy it.

In related development, Apple has not made any comments in regard to iOS 10.1.1 bug, which is causing almost all iPhones and iPads running the latest mobile software to randomly shutdown, despite having close to 30 percent battery power.
